Hey guys,
say i have some standard propagators then I know how to combine them using Feynman's parameter method. But what do I do if one of these propagators is linear?
For instance:
[tex]\int d^Dk \frac{1}{(k-p)^2(k \cdot q)}[/tex]
where q and p are some momenta. How do I combine them?
Does anyone have an idea about that?
Cheers,
